For a dilute solution containing a nonvolatile solute, the molar mass of solute evaluated from the elevation of boiling point is given by the experssion:

Options

A. `M_(2) = (DeltaT_(b))/(K_(b)) (m_(1))/(m_(2))`
B. `M_(2)=(DeltaT_(b))/(K_(b))(m_(2))/(m_(1))`
C. `M_(2) =(K_(b))/(DeltaT_(b)) (m_(2))/(m_(1))`
D. `M_(2) = (K_(b))/(DeltaT_(b)) (m_(1))/(m_(2))`

Answer

C

Explanation

`DeltaT_(b) = (K_(b)m_(2))/(M_(2)m_(1))`
